help with security issue

I'm having trouble debugging a security issue one of my
users is experiencing. The application works fine for the other 25 users.

when the user tries to open a form stored in the SharePoint library, they get the following error:

form template: https://mysite.com/xxx Your user name or
group cannot be verified because your security settings do not permit
it.

The user is running windows xp/infopath 2003 . .net framework is 1.1.
(same as everybody else)

The development environment is Visual Studio 2003, VB, Infopath
2003. The sharepoint site is 2003. The form is published to a
sharepoint library. the form is not full trust - i don't want to make
it full trust unless i have too.

The script behind the infopath form reads an environment variable to
get the username ( Dim txtUserName = Environment.UserName). i'm
sure this code causing the security issue.

i checked in IE Tools/Internet Options/Security/Local intranet/sites/
advanced - the url of the site is in the list, so that's not the
problem. this is typically the issue when user report this type of
problem, but apparently not this time.

I ran Administration Tools/Microsoft .NET Framework Configuration - I
check the Permission Sets for Environment Variables under
LocalIntranet for enterprise/machine/user. it's READ for all of them,
so that should be ok.

so....i'm completely out of ideas.

anybody?!

thanks in advance......
